Was the appearance of Patrice Rushen with Prince on SNL's anniversary show a one-time gig for her? Were there plans for her to continue as a member of his band at that time?

I read somewhere that he wrote "I Feel4 U",,,for Patrice to sing....though she never did-it was liner notes, I think "The Hits-The B-Sides"...you'd have to dbl check me there...Prince liked her voice, the way I recall the story.
